The aggregate capacity of wireless mesh networks is severely affected by interflow interference. Directional antennas and multiple channels are two well known techniques which can be applied to mitigate interflow interference. In this work, a network architecture is proposed to incorporate directional antennas with multiple orthogonal channels effectively to enhance the performance of wireless mesh...
In this work, we study a link-weighted and distance-constrained channel assignment problem in multi-channel mesh networks with stationary router nodes, such as community wireless networks. A good channel assignment is given as the one which can minimize interference of each link from its neighboring links and subsequently improve the network throughput. In response to it, we introduce an interference...
Mesh networks are characterized by the use of multiple channels and multiple interfaces to improve the system throughput. A multi-interface multi-channel wireless mesh network consists of a number of stationary or minimally mobile wireless routers, forming a multi-hop Internet backbone. Previous research has revealed that single channel IEEE 802.11 MAC protocols are not suitable for multihop network...
Channel assignment algorithms revealed so far in the literature for multi-radio multi-channel wireless mesh networks (MRMC-WMN) mainly deals with orthogonal channels (non-overlapped channels). But considering the total number of available orthogonal channels in the case of IEEE 802.11b, which is limited to only 3 channels. Therefore, this lack of availability of assignable channels causes inefficient...
Wireless mesh networks (WMN) is one of the attractive wireless technologies which is expected to be the best alternative for the current wired broadband Internet access. WMNs use a completely wireless distribution system which can provide a good level of coverage, reliability and scalability. Multichannel Multi-radio nodes can be used in the WMNs to enhance the capacity of the network. However, due...
